Snail? Slug? from Alaska

August 7, 2002
From: Clinton Bauder

Hi Bill,
So with this one I'm going to display my complete igorance of all things with shells. Not sure if this guy even belongs on your site but one thing's for sure, I don't know what it is! There were lots of them at Coronation Island in Alaska, July 2002. Depth was about 12m. Size was maybe 60-70mm.

PS: In late breaking news Jeff Goddard tells me the snail is probably Velutina plicatilis but might be V. prolongata. The original descriptions were based on shells making ID of a live animal from a photo problematic

NOTE: See Jim McLean's 7 Sept 2002 message identifying this as Velutina prolongata Carpenter, 1864.

Dear Clinton,
I've added your PS to your original message. Before your PS arrived, a number of us here at the museum had been puzzling over your photo. We had wondered about it being a velutinid but basically felt that without an animal we couldn't identify it. Since getting your PS I have tried, without success, to find an illustration of a living Velutina. I didn't realise the shell of species of Velutina was so exposed. The Velutinidae is a family which now includes those snails, with internal shells, which we used to place in the family Lamellariidae (Lamellaria, Coriocella etc) and are often mistaken for nudibranchs. I look forward to any further comments on this animal's identity
Best wishes,
Bill Rudman
